The study is based on a descriptive statistical approach aimed at analysing and processing hydrogeochemical data of groundwater draining the geological formations of the Beni Hassan Dorsal. The study area is located in the northern part of Morocco, in the Northern Rif. The latter is part of the Flyschs nappes and part of the calcareous dorsal of the Rifaine chain to the south-east of the city of Tetouan. The formations of the main calcareo-dolomitic and detrital geomorphological units constitute an important reservoir in the study area. An inventory of the main resurgences of water points was carried out around the Dorsal and the sandstone massif. Consequently, 7 water points (including 6 springs and 1 well) were the subject of an in situ physico-chemical measurement, a chemical analysis in the laboratory, and in addition a hydrogeological study. The main water springs in the studied area spring up along abnormal contacts of the calcareo-dolomitic Dorsal with impermeable formations. Aquifers in the study area are generally of two types, depending on their physical attributes. They are therefore two types of natural groundwater reservoirs: fissured aquifers and aquifers in porous media. Generally speaking, from a chemical standpoint, the groundwater in the study area is less mineralized to moderately mineralized and shows bicarbonate-calcium chemical facies.

The study is based on a descriptive statistical approach aimed at analysing and processing hydrogeochemical data of groundwater draining the geological formations of the Beni Hassan Dorsal. The study area is located in the northern part of Morocco, in the Northern Rif. The latter is part of the Flyschs nappes and part of the calcareous dorsal of the Rifaine chain to the south-east of the city of Tetouan. The formations of the main calcareo-dolomitic and detrital geomorphological units constitute an important reservoir in the study area. An inventory of the main resurgences of water points was carried out around the Dorsal and the sandstone massif.

Abstract: (french)
L’étude est fondée sur une approche statistique descriptive visant à analyser et traiter les données hydrogéochimiques des eaux souterraines drainant les formations géologiques de la Dorsale de Beni Hassan. Le secteur-objet d’étude se situe au Nord du Maroc, dans le Rif septentrional. Ce dernier fait partie des nappes des Flyschs et d’une partie de la dorsale calcaire de la chaîne rifaine au Sud-Est de la ville de Tétouan. Les formations des principales unités géomorphologiques calcaréo-dolomitiques et détritiques constituent un important réservoir dans la zone d’étude. Un inventaire des principales résurgences des points d’eau a été réalisé sur le pourtour de la dorsale. Par conséquent, 7 points d’eau (dont 6 sources et 1 puits) ont fait l’objet d’une mesure physico-chimique in situ, d’une analyse chimique au laboratoire, et de surcroît une étude hydrogéologique. Les principales sources d’eau dans le secteur étudié jaillissent le long des contacts anormaux de la Dorsale calcaréo-dolomitiques avec des formations imperméables. Les aquifères de la région d’étude sont généralement de deux types et ce, en fonction de leurs attributs physiques. Il s’agit donc de deux types de réservoirs naturels d’eau souterraine: les aquifères fissurés et les aquifères des milieux poreux. Généralement, du point de vue chimique, les eaux souterraines du secteur-objet d’étude sont de moins minéralisées à moyennement minéralisées et elles montrent des faciès chimiques bicarbonaté-calciques.
